Method for improving discharge resistance of epoxy insulator in gas insulation system
TLDR
In this paper, a method for improving the discharge resistance of an epoxy insulator in a gas insulation system was proposed, in which fluoridation is carried out on the epoxy insulation by using a gas mixture of fluorine gas and nitrogen gas or a mixture of inert gas under the conditions of appropriate temperature and pressure.Abstract:
The invention relates to a method for improving the discharge resistance of an epoxy insulator in a gas insulation system. According to the method, fluoridation is carried out on the epoxy insulator by using a gas mixture of fluorine gas and nitrogen gas or a gas mixture of fluorine gas and inert gas under the conditions of appropriate temperature and pressure in a closed reaction chamber, a fluoridation layer containing C-F bonds is formed on the surface of the epoxy insulator, so that the method is used for improving the discharge resistance of the epoxy insulator. Compared with the prior art, the method disclosed by the invention is simple in processing steps, good in controllability and low in economic cost, the epoxy insulators with arbitrary shapes and dimensions can be uniformly modified in batches, and the method is specially applicable for commercial application.read more
